Is there a voice / messaging app that will work via a wifi connection WITHOUT the need for an Internet connection? For example, two people with phones connected to the same router over wifi, but NO ACCESS to the Internet. I'm assuming apps like Skype would require both devices to be able to communicate with the Skype server to initiate the call, but might allow peer-to-peer afterwards.

I am not interested in making calls or texts to people outside of the wifi network. Does such an app exist?

without any kind of data connection, you cannot communicate to the other person. unless you are conversating in person or via us mail.

Do you understand the difference between the INTERNET and WIFI? It would work over WiFi, but not need a central server, nor would it need a connection to the Internet. If you knew the IP address for the other phone, for example, you could connect with it directly.

I don’t know if there is any local network messaging app for android, but I think it is definitely possible to write such app.

But even if there is no such application, you can always set up your own local XMPP (or some other IM protocol) server (visible only from local network) and use any messaging app which supports XMPP protocol. There are plenty of them.

I was thinking of something along those lines. I suppose the heavy solution would be to use a separate computer with asterisk, but I was hoping to find something with just the phones as hardware. The Android 4.0 software has wifi p2p built in, but I'd hate to limit the solution to that environment.

I did find something that seems to work, but is buggy and requires root access: Serval Mesh

This looks like an incredible project and I hope it continues to progress.

If anyone knows of something similar, please reply.

Wifi != internet... You can setup a wireless LAN to share files between computers / devices, without it being connected to the internet. WIfi is just wireless networking... external internet isn't required...

Try this as an experiment: cancel your service with your Internet provider, but keep the router with wifi. Why pay money for the Internet when you've already got wifi? It's the same thing, right?

Why are you arguing? Ever heard of Local Area Network?

Don’t feed the troll, let’s go back to topic...

How about this application? Have you tried it?
https://play.google.com/store/apps/d....android.ipmsg

It seems there are clients for a whole range of platforms:

EDIT: Never mind, it's only messaging app, no calling
